Description

General part information

TLV9021 Series

The TLV902x and TLV903x are a family of single, dual and quad channel comparators. The family offers low input offset voltage, fault-tolerant inputs and a excellent speed-to-power combination. The family has a propagation delay of 100ns with a quiescent supply current of only 18µA per channel.

The family also includes a Power-on Reset (POR) feature that makes sure the output is in a known state until the minimum supply voltage has been reached. This prevents output transients during system power-up and power-down.

These comparators also feature fault-tolerant inputs that can go up to 6V without damage and with no output phase inversion. This family of comparators is designed for precision voltage monitoring in harsh, noisy environments.
